Piuma head and NW cams
Posted: Thu Apr 19, 2007 8:54 pm
Hello,
I measured the cam timings and would like to ask if I made it right....and timings are what they should be.
(re)Measured at std valve clearance.
In open 54BTDC
In close 1050ABDC
Ex open 64BBDC
Ex close 66ATDC
Lobe centers:
IN 80BBDC
EX 82ABDC
1mm lift:
IN 7 / 45
EX 34 / 30
Camwheels A & S2
Is it reasonable to make adjustable camwheels?
Next week the head is going to "tuner" and he wants to know those degrees.
Regards,
Jori
